Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a position system for interactive gaming device and method using the same, and more particularly to a position system for positioning a wireless controller of the interactive gaming device and method using the same.
  • 2. The Related Art
  • Nowadays, more and more people are amused by varieties of video games or computer games. Taking a computer game for example, conventionally, if a player wants to play the computer game, he firstly has to install game software in a host of a computer. The player controls the game process by peripherals of the computer, such as a mouse, a keyboard, a control handle or the like. All of which connect with the computer. The game process and game information are displayed to the player through a monitor and a speaker or other multimedia output devices. However, as continuous development of technology, interactive gaming devices are provided to the player accompanying with the game software.
  • One example of the interactive gaming devices is disclosed in U.S. patent public No. 2007/0072674 issued Jan. 2, 2006. The interactive gaming device includes a host apparatus connected to a home-use TV receiver via a connection cord, a wireless controller for giving operation data to the host apparatus, and a pair of infrared markers provided on top of the TV receiver and on both sides of the TV receiver. Each infrared marker outputs infrared light forward. The host apparatus is connected to a receiving unit via a connection terminal. The receiving unit is used for receiving operation data that is wirelessly transmitted from the wireless controller.
  • The wireless controller includes an operation section, an imaging information calculation section, a communication section and an acceleration sensor. The operation section includes a plurality of operation buttons defined in a housing of the wireless controller, which the player can use to perform the game process. The imaging information calculation section includes an infrared filter, a lens, an imaging element and an image processing circuit. The infrared filter allows only infrared light to pass therethrough. The lens collects the infrared light which has passed through the infrared filter and outputs the infrared light to the imaging element. The imaging element is a solid-state imaging device such as, a CMOS sensor or a CCD. The imaging element takes an image of the infrared light which has passed through the infrared filter and been collected by the lens, and generates image data. The image data is processed by the image processing circuit. The image processing circuit calculates the positions of the infrared markers in the taken image, and outputs coordinate sets to the communication section.
  • The acceleration sensor detects acceleration in three axial directions of the wireless controller, i.e., the up-down direction, the left-right direction and the front-rear direction. The acceleration sensor allows the inclinations of the wireless controller in the three axial directions to be determined. In addition to the taken image mentioned above, the wireless control determines the acceleration and inclination thereof via the acceleration sensor.
  • The communication section includes a microcomputer, a memory, a wireless module and an antenna. The microcomputer receives the data which is output from the operation section, the acceleration sensor, and the imaging information calculation circuit and stores the data in the memory. The wireless module and the antenna transmit the data stored in the memory to the host apparatus by a wireless technology. The data includes the displacement direction, the inclination and the acceleration of the wireless controller.
  • The host apparatus uses the receiving unit to receive the operation data from the wireless controller in a way of wireless transmission and executes the game process based on the obtained operation data.
  • The interactive gaming device makes use of the imaging information calculation section to collect and calculate the positions of the two infrared markers, and simultaneously uses the acceleration sensor to attain the data of the inclination and the acceleration of the wireless controller. Then, the communication section transmits the data of the displacement direction, the inclination and the acceleration of the wireless controller to the host apparatus to be processed. It can be seen that the interactive gaming device should provide the imaging information calculation section and the acceleration sensor to position the wireless controller. So the manufacture cost of the interactive gaming device is increased. Further more, if the environment around the infrared markers brings infrared interference, the imaging information calculation section will not attain the positions of the two infrared markers exactly. Therefore, the game can't go on.
  • Hence, an improved interactive gaming device is desired to overcome the shortcomings described above.
  • SUMMARY OF THE INVENTION
  • Accordingly, an object of the present invention is to provide a position system for positioning a wireless controller of an interactive gaming device. The position system includes a main apparatus and a wireless controller. The main apparatus includes a first ultrasonic receiving module, a second ultrasonic receiving module, a third ultrasonic receiving module, a first communication module and a first antenna. The wireless controller includes an ultrasonic transmitting module, a second communication module and a second antenna. The first ultrasonic receiving module has a distance from the second ultrasonic receiving module, and the third ultrasonic receiving module has a distance from the first ultrasonic receiving module and the second ultrasonic receiving module. The three ultrasonic receiving modules form a triangle shape. The three ultrasonic receiving modules receive ultrasonic signals sent by the ultrasonic transmitting module of the wireless controller in order that the main apparatus calculates the received transmission times of the ultrasonic signals and obtains a plurality of coordinate values indicating the motion track of the wireless controller, and further recognizes the positions of the wireless controller. The main apparatus and the wireless controller transmit data to each other with the help of the first communication module, the first antenna, the second communication module and the second antenna.
  • The other object of the present invention is to provide a method for positioning the wireless controller of the interactive gaming device, comprising the steps of: sending out a prepared position signal through the second antenna connected to the second communication module of the wireless controller; sending out an initiate position signal through the first antenna connected to the first communication module of the main apparatus after the main apparatus receiving the prepared position signal through the first antenna; initiating the ultrasonic transmitting module of the wireless controller to send out an ultrasonic signal after the second communication module receiving the initiate position signal through the second antenna; receiving the ultrasonic signal by the first ultrasonic receiving module, the second ultrasonic receiving module and the third ultrasonic receiving module; calculating the received transmission time of the ultrasonic signal and obtaining a coordinate value of the wireless controller by the main apparatus; sending out an accomplished position signal by the first communication module through the first antenna; and receiving the accomplished position signal by the second communication module through the second antenna to finish positioning the wireless controller.
  • It can be seen that the main apparatus and the wireless controller transmit data to each other with the help of the first communication module, the first antenna, the second communication module and the second antenna. The first ultrasonic receiving module, the second ultrasonic receiving module and the third ultrasonic receiving module receive the ultrasonic signal sent by the ultrasonic transmitting module of the wireless controller. The main apparatus calculates the received transmission time of the ultrasonic signal and obtains the coordinate value of the wireless controller to position the wireless controller. The structure of the position system for interactive gaming device is simplified, and the manufacture cost is reduced. Moreover, the ultrasonic is uneasy to be interfered, so the wireless controller is positioned more precisely. Therefore, the invention attains the aim of overcoming the drawbacks of the prior art.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • With reference to FIG. 1, a position system for interactive gaming device 100 in accordance with the present invention includes a main apparatus 1 and a wireless controller 2. The main apparatus 1 is connected to an electronic device such as a host of a computer or a gaming device via a connection cord. In the preferred embodiment, the electronic device is a host 3 of a computer. The host 3 is further connected to a display device and the display device is a monitor 4 of the computer in the preferred embodiment. Game software is installed in the host 3, and when a player has a game, the player can control the game process by the wireless controller 2. The main apparatus 1 receives the control signals from the wireless controller 2 and calculates the coordinate values of the wireless controller 2. The main apparatus 1 transmits the control signals and the coordinate values to the game software installed in the host 3 by the connection cord. The game software further controls the game process based on the control signals and the coordinate values of the wireless controller 2, and shows the game process to the player through the monitor 4 connected to the host 3.
  • Please refer to FIG. 2 and FIG. 3. FIG. 2 is a perspective view of the main apparatus 1, and FIG. 3 is a circuit block diagram of the main apparatus 1. The main apparatus 1 includes a first microcomputer 10, a first ultrasonic receiving module 11, a second ultrasonic receiving module 12, a third ultrasonic receiving module 13, a first memory unit 14, a first communication module 15, a first antenna 16 and a first USB module 17. All of these will be described in detail hereinafter.
  • Please refer to FIG. 3 again. The first ultrasonic receiving module 11, the second ultrasonic receiving module 12 and the third ultrasonic receiving module 13 are connected to the first microcomputer 10 respectively, which can transform received ultrasonic signals into data and transmit the data to the first microcomputer 10. The first memory unit 14 connected to the first microcomputer 10 is used for storing data for opening the main apparatus 1. When a power switch of the main apparatus 1 is opened, only when the first microcomputer 10 attains the data for opening the main apparatus 1 from the first memory unit 14, the main apparatus 1 is started to work normally. The first memory unit 14 is also used for storing important data for the first microcomputer 10.
  • The first communication module 15 connects with the first microcomputer 10 and the first antenna 16 respectively. The first communication module 15 receives and modulates instructions from the first microcomputer 10 into wireless signals, and then sends out the wireless signals via the first antenna 16. The first communication module 15 can also receives and demodulates wireless signals from the first antenna 16 into instructions, and then transmits the instructions to the first microcomputer 10. The main apparatus 1 and the host 3 transmit data to each other via the first USB module 17 connected to the first microcomputer 10 and a connection cable which connects the first USB module 17 to the host 3. Additionally, the host 3 can provide power to the main apparatus 1 through the first USB module 17.
  • Referring to FIG. 2, the first ultrasonic receiving module 11, the second ultrasonic receiving module 12 and the third ultrasonic receiving module 13 are defined on the main apparatus 1 respectively. The first ultrasonic receiving module 11 and the second ultrasonic receiving module 12 are on the same level and the distance between them is designated W. The third ultrasonic receiving module 13 is defined at the middle of the first ultrasonic receiving module 11 and the second ultrasonic receiving module 12. The distance from the third ultrasonic receiving module 13 to the level defined by the first ultrasonic receiving module 11 and the second ultrasonic receiving module 12 is designated H. So obviously the first ultrasonic receiving module 11, the second ultrasonic receiving module 12 and the third ultrasonic receiving module 13 are not at the same level and form a triangle shape between them. In the preferred embodiment, the value of the W is 20 centimeters, and the value of the H is at the range of 2 centimeters to 5 centimeters. The specific arrangement of the first ultrasonic receiving module 11, the second ultrasonic receiving module 12 and the third ultrasonic receiving module 13 facilitates the main apparatus 1 detecting the up-down displacement, the left-right displacement and the front-rear displacement of the wireless controller 2. Hereinafter, this will be described in detail.
  • Please refer to FIG. 4 and FIG. 5. FIG. 4 is a perspective view of the wireless controller 2. FIG. 5 is a circuit block diagram of the wireless controller 2. The wireless controller 2 includes a second microcomputer 20, an operation module 21, a second memory unit 22, an ultrasonic transmitting module 23, a second communication module 24, a second antenna 25, a voice output module 27 and a vibrator 28.
  • With reference to FIG. 4, the operation module 21 includes a cross button 210 and a plurality of control buttons 211 defined on a housing of the wireless controller 2. The cross button 210 and the control buttons 211 are endued with different functions in game. The player can press the buttons to control the game process. The ultrasonic transmitting module 23 is defined on the housing of the wireless controller 2. The ultrasonic transmitting module 23 sends out an ultrasonic signal which is received by the first ultrasonic receiving module 11, the second ultrasonic receiving module 12 and the third ultrasonic receiving module 13 in order to facilitate the main apparatus 1 to position the wireless controller 2.
  • Referring to FIG. 5, the operation module 21 is connected to the second microcomputer 20. The second microcomputer 20 detects the press state of the cross button 210 and the control buttons 211 and produces corresponding instructions. The second memory unit 22 connected to the second microcomputer 20 is used for storing data for opening the wireless controller 2. When a power switch of the wireless controller 2 is opened, first of all, the second microcomputer 20 collects the data from the second memory unit 22 to start the wireless controller 2 to work normally. Further more, the second memory unit 22 can store important data for the second microcomputer 20.
  • The ultrasonic transmitting module 23 connected to the second microcomputer 20 sends out an ultrasonic signal according to the instructions which are sent by the second microcomputer 20. The second communication module 24 connects with the second microcomputer 20 and the second antenna 25 respectively. The second communication module 24 receives and modulates instructions from the second microcomputer 20 into wireless signals and then sends out the wireless signals via the second antenna 25. The second communication module 24 can also receives and demodulates wireless signals from the second antenna 25 into instructions, and then transmits the instructions to the second microcomputer 20.
  • The voice output module 27 and the vibrator 28 are respectively connected to the second microcomputer 20. When the game is going on, the main apparatus 1 sends instructions to the first communication module 15. The first communication module 15 receives and modulates the instructions into wireless signals and sends out the wireless signals by the first antenna 16. The second antenna 25 of the wireless controller 2 receives the wireless signals sent by first antenna 16 of the main apparatus 1, and sends the wireless signals to the second communication module 24. The second communication module 24 receives and demodulates the wireless signals into instructions, and sends the instructions to the second microcomputer 20. The second microcomputer 20 distinguishes the instructions and directs the voice output module 27 and the vibrator 28 to output voice and vibration which improve the fun of the game as if the player were a part of the game.
  • Referring to FIG. 6, after the player starts the main apparatus 1 and the wireless controller 2, the main apparatus 1 begins to position the wireless controller 2, and data is transmitted between the main apparatus 1 and the wireless controller 2. The transmission speed of an ultrasonic wave is 340 m/s on condition that the temperature is 25 degrees and the transmission medium is air. In the process of the main apparatus 1 positioning the wireless controller 2, the wireless controller 2 can be shifted in a better area defined by a longitudinal distance labeled D1 from the main apparatus 1 and a transverse distance labeled D2. In this area, the main apparatus 1 positions the wireless controller 2 precisely. In the preferred embodiment, the value of the D1 is 5 meters, and the value of the D2 is 10.5 meters.
  • For example, if the distance between the wireless controller 2 and the main apparatus 1 is 2 meters, that is, the value of the D1 is 2 meters, it can be seen that after the wireless controller 2 sends an ultrasonic wave, the time that the main apparatus 1 receives the ultrasonic wave is approximate 5.8 microseconds based on the transmission speed of the ultrasonic wave. However, the ultrasonic transmitting module 23 of the wireless controller 2 needs 1 microsecond to produce an ultrasonic wave. So the wireless controller 2 needs 6.8 microseconds to send an ultrasonic wave.
  • If the distance between the wireless controller 2 and the main apparatus 1 is 5 meters, that is, the value of the D1 is 5 meters, it can be seen that after the wireless controller 2 sends an ultrasonic wave, the time that the main apparatus 1 receives the ultrasonic wave is approximate 14.7 microseconds according to the transmission speed of the ultrasonic wave. That is, if the number of the wireless controller 2 increases, the times of the main apparatus 1 detecting the position of every wireless controller 2 decreases correspondingly.
  • Please refer to FIG. 7 and FIG. 8. FIG. 7 shows the first time that the main apparatus 1 positions the wireless controller 2. FIG. 8 is a flow chart of an embodiment of the first time that the main apparatus 1 positions the wireless controller 2. In this embodiment, a method for positioning the wireless controller 2 of the interactive gaming device is described as follows:
    • 1) After the wireless controller 2 is opened and starts to work, the player presses the cross button 210 or the control buttons 211. Then, the second microcomputer 20 detects the press state of the buttons, and then sends a prepared position instruction which means preparing to be positioned to the second communication module 24. The second communication module 24 receives the prepared position instruction and modulates the position instruction into a wireless signal which is sent out by the second antenna 25.
    • 2) The first antenna 16 of the main apparatus 1 receives the wireless signal sent by the wireless controller 2 and transmits the wireless signal to the first communication module 15. The first communication module 15 receives and demodulates the wireless signal into an instruction, and sends the instruction to the first microcomputer 10. The first microcomputer 10 tests the instruction to confirm that the instruction is right. Then the first microcomputer 10 sends an initiate position instruction to the first communication module 15. The first communication module 15 receives the initiate position instruction and modulates the initiate position instruction into an initiate position wireless signal which is sent out by the first antenna 16.
    • 3) When the second antenna 25 receives the initiate position wireless signal, the initiate position wireless signal is sent to the second communication module 24. The second communication module 24 receives and demodulates the initiate position wireless signal into an initiate position instruction, and sends the initiate position instruction to the second microcomputer 20. The second microcomputer 20 receives and tests the initiate position instruction. If the initiate position instruction is accurate, the second microcomputer 20 orders the ultrasonic transmitting module 23 to send out an ultrasonic signal.
    • 4) The first ultrasonic receiving module 11, the second ultrasonic receiving module 12 and the third ultrasonic receiving module 13 respectively receive the ultrasonic signal sent by the wireless controller 2. The transmission time of the ultrasonic signal to the three ultrasonic receiving modules 11, 12, 13 are labeled Ta, Th, Tc respectively. The first microcomputer 10 calculates the beeline distances between the wireless controller 2 and the first ultrasonic receiving module 11, the second ultrasonic receiving module 12, the third ultrasonic receiving module 13 according to the transmission characteristic of the ultrasonic wave after receiving the time Ta, Tb, Tc information. Then the main apparatus 1 attains a coordinate value of the wireless controller 2 and positions the wireless controller 2. After then, the main apparatus 1 considers the coordinate value as a basic point, and sends a complete position instruction to the first communication module 15. The first communication module 15 receives and modulates the complete position instruction into a complete position signal sent out by the first antenna 16. The second antenna 25 receives and transmits the complete position signal sent by the main apparatus 1 to the second communication module 24. The second communication module 24 receives and demodulates the complete position signal into the complete position instruction, and transmits the complete position instruction to the second microcomputer 20. Then the second microcomputer 20 tests the instruction and confirms that the complete position instruction is right. The first time that the main apparatus 1 positions the wireless controller 2 is accomplished.
  • Please refer to FIG. 9, which is a flow chart of another embodiment of the first time that the main apparatus 1 positions the wireless controller 2. In this embodiment, the method that main apparatus 1 positions the wireless controller 2 is described as follows:
    • 1) After the wireless controller 2 is opened and starts to work, the player presses the cross button 210 or the control buttons 211. Then, the second microcomputer 20 detects the press state of the buttons, and sends a prepared position instruction which means preparing to be positioned to the second communication module 24. The second communication module 24 receives the prepared position instruction and modulates the position instruction into a wireless signal which is sent out by the second antenna 25.
    • 2) The first antenna 16 of the main apparatus 1 receives the wireless signal sent by the wireless controller 2 and transmits the wireless signal to the first communication module 15. The first communication module 15 demodulates the wireless signal into an instruction, and sends the instruction to the first microcomputer 10. The first microcomputer 10 tests the instruction to confirm that the instruction is right. Then the first microcomputer 10 sends an initiate position instruction to the first communication module 15. The first communication module 15 receives the initiate position instruction and modulates the initiate position instruction into an initiate position wireless signal. The first antenna 16 sends out the initiate position wireless signal, and at the same time, the first microcomputer 10 starts a procedure for timing.
    • 3) When the second antenna 25 receives and sends the initiate position wireless signal to the second communication module 24.
